Clinical Trial Summary

This phase 2 study aim to investigate the effect of dobutamine in patients with sepsis/ septic shock after fluid resuscitation and with hypoperfusion (lactate and central venous oxygen saturation or prolonged capillary refill time) on renal function as compared with usual care.

Description:

In this phase 2 study patients with sepsis/ septic shock and signs of persistent hypoperfusion after fluid resuscitation will be randomized to receive either dobutamine or no intervention in addition to usual care. Dobutamine will be used for 48 hours. Hypoperfusion will be assessed by altered lactate levels and a low SvO2 or prolonged capillary refill time. Both arms will receive usual care according to the Surviving Sepsis Campaign guidelines. Dobutamine dosis will be adjusted to achieve improvement in the perfusion parameters according to a pre specified protocol. Pre specified criteria will be used to stop the drug for safety. The primary outcome will be creatinine at Day 3. Other secondary and safety outcomes will also be assessed.
